* An extension point was created, which enables the invocation of other ATL Virtual Machines from the launch configuration or ATL ant tasks. The list of ATL VM available is located in the advanced tab

+

A new ATL VM dedicated to EMF has been included in this release, which strongly increase performances. There is still missing features, so there is a page for watch and report developments around the EMFVM : [EMFVM testing http://wiki.eclipse.org/ATL_VM_Testing].

−

* Added accessor to ATL resourceSet (may, for instance, be used by other tools to access ATL-registered metamodels)

+

This page show the results of the new ATL regression test, which checks the validity of old transformation by reusing the [ATL Transformation Zoo http://www.eclipse.org/m2m/atl/atlTransformations/]. The resulting models are compared using [EMFCompare http://wiki.eclipse.org/index.php/EMF_Compare].

−

* Added a Problem target model to the ATL compiler so that it may report problems more appropriately

Eclipse Ganymede compatibility

The ATL Toolkit is now compatible with Eclipse Ganymede (Eclipse 3.4, EMF 2.4).

ANTLR 3.0 support

The ATL Toolkit is now using ANTLR 3.0. ANTLR 3.0 Runtime has been approved by Eclipse Foundation (see IPzilla CQ 1548, in which this was approved).
ANTLR 2.X dependency has been removed and ANTLR 3.0 is externalized in a plugin, installed from an Orbit package. From user point of view, this simplifies ATL installation.

Language Improvement

Support for specification of source model(s) to match a source element in.

It is possible now to define attribute helpers in ATL libraries.

allInstances return value has been changed from Set to OrderedSet.

A new feature is available : ATL Superimposition. Superimposition allows you to load an ATL transformation module on top of another in your "Run..." configuration. It allows for the superimposing module to import and override matched rules from the module it is superimposed upon. More details are available here: http://wiki.eclipse.org/ATL_Superimposition

Content assist

To make model elements completion available, you have to put some information on the top of the file :

-- @nsURI : the nsURI for a given metamodel, if you want to load a metamodel from the EMF registry,

-- @path : the path of a given metamodel, if you want to dynamically load a metamodel from an ecore file.

Only EMF metamodels are supported. You must spécify the relative path of the file into the workspace.
